Hostile territory

The Diamondbacks haven't played at Safeco Field since 2009 -- before any of their current players were wearing Sedona Red. They were swept in that series (the losing pitchers were Clay Zavada, Billy Buckner and Tony Pena), are 2-7 all-time at Seattle and 7-14 all-time vs. the Mariners.

It starts with the starters

The Diamondbacks got their best stretch of starting pitching of the season in taking 3 of 4 games from the Brewers. Their four starters gave up one run in 27 innings (an ERA of 0.33), and they posted back-to-back shutouts of Milwaukee on Saturday and Sunday. The D-backs have never registered three consecutive shutouts.

Advantage: D-backs

The Mariners hoped to enhance their playoff chances by trading for Mark Trumbo in the first week of June to beef up a feeble lineup, but the trade has backfired so far. Trumbo has three home runs, a .212 average and 43 strikeouts in 137 at-bats for Seattle; he had nine homers, a .259 average and 39 strikeouts in 174 at-bats for the D-backs. Catcher Welington Castillo, acquired by Arizona in the deal, is hitting .269 with five home runs since the trade.

Don't blame Inciarte

The D-backs have needed all the help they can get from the pitching of late due to an uncharacteristic offensive slump. They've scored more than three runs only once in their past eight games. Just don't blame Ender Inciarte. He's 14 for 36 (.389) since returning from the disabled list and has doubled in five consecutive games. Robinson Cano is swinging a hot bat for the Mariners, with four home runs, 11 RBI and a .350 average to break out of a season-long slump.
